I use backintime for my local backups. It keeps history of files, so even if you accidentally alter a file and discovers a month later, you can recover the last version. If you have a VPS somewhere, like me, you can use syncthing or owncloud too. They are very good for backups. I keep a local backintime backup, rsync to a raspberry pi every night, and sync it to the VPS every week. On Dec 23, 2016 5:21 PM, "William Park via talk" <talk@gtalug.org> wrote:
My recommendations...
1. Backup entire disk to another disk, verbatim. That is, dd if=/dev/sdX of=/dev/sdY bs=10M
First, you don't have to waste time figuring out what to back up. Second, if disk fails, you can just swap the disks, and copy over only the new files since last dd.
2. Backup entire /home to another disk. That is, mount /home/sdZ /mnt/home rsync -aHxv -SAX /home/ /mnt/home/ --delete --exclude='/*/.gvfs'
Again, I would copy the whole things. If you have somethings that you don't want to backup, then you can put them in /home/dont_backup, and add it to exclude list, --exclude='/dont_backup'
3. If your /home is on BTRFS filesystem, you can take snapshots, like btrfs subvolume snapshot -r home home--$(date +%F)
Harddisk is "cheap", and snapshot is "cheaper". -- William
Hi everyone,
I'm backing up my system on a more regular basis and am trying to fine tune the files that I backup. I am looking for advice on what NOT to bother to backup on the /home directory.
I am using rsync (took a long time and lots of trials to figure out the man page - and still don't know 90% of it) and presently have the following on my exclude_list.txt: (Note: multiple items shown on one line are just for readability, each

I'd love to exclude things that perhaps one would never use from a backup to rebuild a system after an accidental clean wipe of all data.
Similarly, any recommendations of what I should back up outside of /home? I am thinking of things like /etc/fstab, files that would make it easier to recover from a crash or to upgrade a distro.
Thanks for any advice.
